1 For elegant interior and exterior car design

2 A unique combination of expertise and innovative spirit Constellium is a global sector leader that develops innovative, value added aluminium products for a broad scope of markets and applications, including aerospace, automotive and packaging. In our P&ARP (Packaging & Automotive Rolled Products) Singen plant, we produce and develop aluminium sheets and coils with advanced bright and functional surfaces for a wide range of applications such as lighting, solar, automotive, decorative and cosmetics. Our customers rely on our products for elegant car design. Innovation is at the heart of our business and our dedicated multidisciplinary teams constantly develop new surfaces from our world class R&D centre in Voreppe combined with our industrial capabilities in our Singen plant.

3 Production process Constellium process Aluminium is smelted by electrolysis Slab casting in anodizing quality In-line reversible hot rolling Water quenching Cold rolling Optional annealing Cold rolling with highly polished cylinders Optional annealing Finishing operations Customer process Bright Shaping, punching, drilling, milling, brushing, etc. Matt Anodizing, coating, injection moulding and assembly Structured Our innovation capabilities Constellium s process simulation Customer s process simulation R&D analysis Casting unit Hot and cold semi-industrial rolling mills Surface treatment on continuous or batch line Formability lab Microscopic analysis We can prototype new alloys for new applications from casting to finishing. We are equipped with all machines necessary to transform the alloys into strips and sheet products and apply all thermal treatments. We can simulate the customer s anodizing and surface treatment processes, such as coating. We can numerically model and simulate the customer s forming process, and perform formability and assembly tests, such as stamping and direct injection moulding. We can understand the alloy structure and recommend improvements based on the microscopic analysis.
